Description

The GWR Viaduct, possibly built in the 1880s, features granite piers that support eight arches made of engineering brick. It spans over a tidal mill, with three of its piers located in the pond. The viaduct is attractively positioned at the mouth of the Forder Estuary, situated below Trematon Castle and elevated above the Tidal Corn Mill.

Gwr Viaduct sits in a wetter-than-average part of the UK, with an average of 990 mm of rain a year. This makes it wetter than 80% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 89% of listed buildings.

It experiences an average of 9 freeze-thaw cycles a year, fewer than 91% of listed buildings. Of these, 3 follow at least 1 mm of rain in the preceding 48 hours. Average temperatures at this location have risen by 0.3°C per decade since 1991.
